A new therapy being tested is giving excellent results in blocking hunger in patients suffering from mild and moderate obesity: it is a partial cryotherapy of the vagus nerve , which would be partially frozen with an intervention of about half an hour, completely painless, interrupting the nerve connections that communicate with the brain and regulate the sense of hunger.

According to Dr. David Prologo, head of the experimental therapy conducted by the Emory University School of Medicine , this small intervention on the vagus nerve, which consists in its partial freezing, would allow to block hunger in people who are unable to eat less, and accumulate so unwanted weight over the years.
The results of the therapy to block hunger are quite promising: freezing part of the vagus nerve, leading to its partial degeneration, would allow those obese patients who do not meet the criteria for bariatric surgery to lose weight without effort, within three months. .

The ten patients who underwent the procedure would have been able to lose an average of 3.6% of their initial body weight without a diet (for a subject weighing 100 kilos, this means having lost about 3.6 kilos in three months without eating otherwise: this means that in a year you would lose an average of 13 kilos, but that it would also be easier to follow a diet, obtaining greater results ), but simply feeling less hunger. The excess body mass index would have dropped 14 points on average. All patients report feeling less hungry. However, the procedure to block hunger with cryoablation is not permanent, i.e. it should be repeated once a year because the frozen part of the vagus nerve regenerates itself in about a year.
